300W ATX Replacement Unit

This 300W ATX power supply replaces FSP FSP300-60GRE, FSP300-60PLN and FSP300-60THN models. It fits standard ATX chassis and suits owners of compatible Dell, HP or similar desktops needing a direct swap. The grey unit weighs 0.1 kg and includes a single cooling fan. It targets system integrators and home users restoring legacy office or home PCs.

Build Integration

The unit provides one 20+4-pin ATX connector, one 4-pin ATX12V connector, two peripheral connectors, one floppy connector and three SATA connectors. This complement covers a typical motherboard, CPU, three SATA drives and legacy peripherals without adapters. A single fan handles airflow, leaving cable routing straightforward in compact cases. Builds requiring additional PCIe power or more than three SATA devices cannot use this unit.

300W Continuous Capacity

Rated at 300W steady output, the supply handles mainstream desktop loads including integrated graphics and multiple storage drives. High efficiency and low ripple protect components during sustained operation. Over-voltage protection guards connected hardware. Systems with discrete graphics cards, high-core-count CPUs or heavy peripheral counts will exceed the available headroom.

Questions about this item

What is the maximum continuous output this 300W unit can deliver?

The supply is rated for 300 watts of steady power, which is the ceiling you will hit first when the system draws full load for extended periods.

How loud and hot does the single fan get during all-day operation?

One fan handles cooling; the design targets low ripple and noise, so acoustics and temperatures stay modest under typical desktop workloads.

Which motherboard power connectors must my board already have for this supply to work?

You need a 20+4-pin ATX socket and a 4-pin ATX12V socket on the motherboard; the unit also provides two peripheral, one floppy and three SATA power leads for drives.
